Best Answer

field coils generally refer to the electromagnetic coils on the stator ( the stationary part of an electric motor ). these generate the magnetic field(s) necessary to put the rotor ( the rotating part of the motor ) into motion.

What is the definition of a core in electrical equipment?

A core in the electrical trade usually refers to the iron laminations that coils of wire are wrapped around. The core directs the magnetic field, that the coils of wire produce when energized, into a working force. This could be the iron core of a relay or a transformer core that is the centre and principle reason that a transformer can operate.

How wireless chargers are working?

Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer. Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.

Nichrome


How do you use a multimeter tester on dryer coils?

Generally, dryer coils either work or they don't. A multimeter can help you determine if a dryer coil is "burned out". If the coil has "continuity", it's probably fine. Generally, if there is a hot spot in the coil it will burn out rapidly.

Why does shunt generators produce only DC signal or emf?

This is in the wiring, the armature(s) field coils, etc, by the way if DC it would have permanent ( fixed) field magnets, not field coils. ac motors have Field coils, not to be confused with Field Amperage or Primary Coils- the latter being the (heart) of a transformer, consult Audels or similar technical shop manuals.


What effect does increasing the number of coils have on an electromagnet?

Adding more coils will make the magnetic field stronger. Magnetic field increases.


How the magnetic field of an electromagnet defends on the current and the number of coils?

The magnetic field of an electromagnet is directly proportional to both the current passing through its coils and the number of coils. Increasing either the current or the number of coils will result in a stronger magnetic field, while decreasing them will weaken the magnetic field. This relationship is described by Ampere's law and the concept of magnetic flux.


What is the effect of adding more coils of wire to an electromagnetic?

Increasing the coils will increase the strength of the magnetic field.


What happens to an electromagnet when electricity runs through it?

When an electric pulse runs through an electromagnet, the current travels in the electromagnets coils, causing a magnetic field to be developed inside and outside of the coils. The amount of coils, tightness of the coils, and the space between the coils are all very important factors in the production of said EM field.


How could you produce a magnetic field using a wire?

Any time an electric current passes through a wire, this will produce a magnetic field. If you want to make the field stronger, loop the wire into coils. The more coils you make, the stronger the field will be.


How can the field coils of a dc machine be connected with self excitation?

No


How is solenoid a magnet?

A Solenoid is an electro-magnet. It has coils of wire, usually copper. When an electric field is applied to the coils of wire, an magnetic field is generated. This magnetic field attracts a steel or iron segment on the switch and activates the switch.


What would increase the strength of the magnetic field?
